Pigeon,
J.
(all
concur)
:—In
1963
and
1964
appellant,
then
known
as
Monarch
Fine
Foods
Limited,
was
manufacturing
margarine.
By
its
petition
of
right
it
seeks
to
recover
the
sum
of
$355,412.48
paid
under
protest
for
sales
tax
in
respect
of
the
sale
of
this
product
between
April
7,
1963
and
February
8,
1964.
The
claim
for
exemption
is
based
on
the
contention
that
because
a
substantial
proportion,
varying
between
48%
and
90%,
of
the
oil
used
as
the
main
component
in
the
manufacture
of
this
butter
substitute
was
herring
oil,
it
is
to
be
considered
as
an
edible
product
of
fish
within
the
meaning
of
the
following
item
of
Schedule
III
of
the
Excise
Tax
Act
under
the
heading
“Foodstuffs”
:
“Fish
and
edible
products
thereof
;”
Cattanach,
J.
dismissed
the
petition
saying
:
In
my
view,
in
order
to
determine
whether
a
particular
product
falls
within
an
expression
such
as
“Fish
and
edible
products
thereof;”
resort
must
be
had
to
the
common
understanding
of
such
words
when
used
in
relation
to
articles
of
commerce.
The
question
here
is,
therefore,
whether,
in
the
ordinary
use
of
words,
margarine
may
be
fairly
regarded
as
falling
within
the
words,
“Fish
and
edible
products
thereof;”
or
more
specifically,
applying
such
a
test:
is
margarine
a
product
of
fish?
I
do
not
think
that,
in
common
parlance,
the
words
“product
of
fish”
can
be
considered
as
comprehending
margarine,
even
though
it
contains
fish
oil
as
one
of
its
principal
ingredients.
Margarine
is
itself
a
well
known
article
of
commerce
and
is
neither
marketed,
purchased,
nor
thought
of
by
the
consumer
as
a
product
of
fish.
It
seems
to
me
that
the
fish
from
which
oil
has
been
extracted
and
which
is
used
in
the
manufacture
of
margarine,
which
is
by
no
means
the
sole
ingredient
of
the
end
product,
has
become
so
obscured
by
the
processes
to
which
it
and
the
oil
thereof
has
been
subjected
and
by
the
oil
being
intermingled
with
substantial
amounts
of
other
ingredients
from
other
sources,
the
whole
of
which
is
again
the
subject
of
an
extensive
manufacturing
process,
that
the
resultant
margarine
cannot
be
considered
as
a
product
of
fish,
even
though
the
fish
oil
content
may
make
the
margarine
a
fish
oil
margarine
and
the
labels
thereon
disclose
the
fish
oil
content.
Counsel
for
the
appellant
pointed
out
that
before
reaching
the
above
stated
conclusion,
the
trial
judge
had
made
a
finding
‘‘that
any
margarine
40%
or
over
of
the
total
oil
content
of
which
is
fish
oil
is
referred
to
in
the
trade
as
a
fish
or
marine
oil
margarine’’.
It
must
be
noted
however
that
this
designation
does
not
appear
to
be
used
in
connection
with
retail
sales.
Fish
or
marine
oil
margarine
is
not
sold
to
consumers
as
a
fish
product
and
is
almost
invariably
sold
with
dairy
products
in
the
same
way
as
vegetable
oil
margarine.
A
trade
designation
in
such
limited
use
cannot
be
considered
as
of
substantial
weight
in
ascertaining
the
proper
description
of
the
goods
for
the
purposes
with
which
we
are
concerned.
Reference
was
made
to
the
decision
of
this
Court
in
T'ownsend
v.
Northern
Crown
Bank
(1914),
49
S.C.R.
394.
In
that
case,
the
question
was
whether
sawn
lumber
was
a
“product
of
the
forest’’
within
the
meaning
of
Section
88
of
the
Bank
Act.
Duff,
J.
(as
he
then
was)
said
(at
p.
398)
:
This
is
only
one
example
of
the
class
of
cases
in
which
the
court
being
loath
and
refusing
to
attempt
to
draw
an
abstract
line,
finds
itself
compelled
to
decide
whether
a
particular
concrete
case
falls
on
one
side
or
on
the
other
side
of
the
line
which
theoretically
must
be
found
somewhere
within
given
limits.
In
this
particular
case
I
prefer
to
say
that
according
to
the
common
understanding
the
articles
in
question
would
fairly
be
comprised
within
the
description
“products
of
the
forest”,
and
I
think
they
are
within
the
contemplation
of
the
enactment
we
have
to
interpret.
In
my
view,
the
trial
judge
applying
this
test
was
fully
justified
in
reaching
the
conclusion
that
according
to
the
common
understanding
margarine
was
not
a
product
of
fish,
even
when
in
specialized
trading
circles
a
particular
kind
was
known
as
fish
oil
margarine.
Furthermore,
although
in
some
cases
fish
oil
was
the
main
raw
material,
in
other
cases
and
for
a
very
substantial
quantity
it
was
only
approximately
one
half
the
main
raw
material,
it
being
mixed
with
an
equal
or
nearly
equal
quantity
of
vegetable
oil.
Also,
it
was
shown
that
all
the
fish
oil
used
was
treated
to
remove
any
odour
or
colour
identifying
it
with
fish
so
that,
for
the
consumer,
the
product
would
be
undistinguishable
from
margarine
made
from
vegetable
oil
only.
Finally,
the
refined,
bleached
and
deodorized
oil
was
hydrogenated,
a
process
altering
its
chemical
nature
to
such
extent
that,
as
Dr.
Sims
said,
it
was
‘‘no
longer
a
fish
oil,
but
a
derivative
of
fish
oil”.
In
his
argument
in
support
of
the
judgment
of
the
Exchequer
Court,
counsel
for
the
respondent
made
reference
to
the
new
Schedule
III
to
the
Excise
Tax
Act
substituted
for
the
former
one
by
Section
8
of
14-15
Eliz.
II,
c.
40
(assented
to
July
11,
1966).
One
of
the
new
items
is
the
following:
20.
Oleomargarine
and
margarine
for
consumption
in
the
Province
of
Newfoundland.
It
was
contended
that
this
amendment
of
the
statute
could
be
considered
in
construing
the
former
text
on
the
same
basis
as
this
Court
did
consider
an
amendment
of
a
zoning
by-law
in
construing
its
original
provisions
in
Wilson
v.
Jones,
[1968]
S.C.R.
554.
I
must
point
out
that
the
two
situations
are
entirely
different.
In
the
Wilson
case,
the
amending
by-law
had
been
adopted
long
before
the
application
for
the
building
permit
sought
to
be
enjoined.
Therefore,
the
amending
by-law
was
to
be
considered
as
making
one
enactment
together
with
the
original
by-law.
In
the
present
case,
however,
the
tax
sought
to
be
recovered
was
paid
in
1963
and
1964
and
the
petition
of
right
filed
in
March
1964,
long
before
the
amending
statute
was
enacted.
In
the
absence
of
any
declaratory
provisions,
the
1966
statute
cannot
have
any
retrospective
operation
and
the
construction
of
the
schedule
as
it
stood
at
the
material
time
can,
in
no
way,
be
affected
by
the
later
amendment.
The
appeal
should
be
dismissed
with
costs.
